Big-data approaches lead to an increased understanding of the ecology of animal movement

Science, Journal Year: 2022, Volume and Issue: 375(6582)

Published: Feb. 17, 2022

Understanding animal movement is essential to elucidate how animals interact, survive, and thrive in a changing world. Recent technological advances data collection management have transformed our understanding of "movement ecology" (the integrated study organismal movement), creating big-data discipline that benefits from rapid, cost-effective generation large amounts on movements the wild. These high-throughput wildlife tracking systems now allow more thorough investigation variation among individuals species across space time, nature biological interactions, behavioral responses environment. Movement ecology rapidly expanding scientific frontiers through interdisciplinary collaborative frameworks, providing improved opportunities for conservation insights into wild animals, their causes consequences.

A guide for studying among-individual behavioral variation from movement data in the wild

Movement Ecology, Journal Year: 2020, Volume and Issue: 8(1)

Published: June 29, 2020

Animal tracking and biologging devices record large amounts of data on individual movement behaviors in natural environments. In these data, ecologists often view unexplained variation around the mean as "noise" when studying patterns at population level. field behavioral ecology, however, focus has shifted from means to biological underpinnings means. Specifically, use repeated measures behavior partition variability into intrinsic among-individual reversible plasticity quantify: a) types (i.e. different average expression), b) responsiveness individuals environmental gradients), c) predictability residual within-individual mean), d) correlations among components suites behaviors, called 'behavioral syndromes'. We here suggest that partitioning animal movements will further integration ecology with other fields ecology. provide a literature review illustrating differences are insightful for wildlife conservation studies give recommendations regarding required addressing such questions. accompanying R tutorial we guide statistical approaches quantifying aspects variation. 35 African elephants show differ their three common rate which they adjusted over temporal gradient, (ranging more less predictable individuals).

Ecological impacts of human‐induced animal behaviour change

Ecology Letters, Journal Year: 2020, Volume and Issue: 23(10), P. 1522 - 1536

Published: July 24, 2020

Abstract A growing body of literature has documented myriad effects human activities on animal behaviour, yet the ultimate ecological consequences these behavioural shifts remain largely uninvestigated. While it is understood that, in absence humans, variation behaviour can have cascading species interactions, community structure and ecosystem function, we know little about whether type or magnitude human‐induced translate into detectable change. Here synthesise empirical theory to create a novel framework for examining range behaviourally mediated pathways through which may affect different functions. We highlight few studies that show potential realisation some pathways, but also identify numerous factors dampen prevent consequences. Without deeper understanding risk wasting valuable resources mitigating with relevance, conversely mismanaging situations do drive The presented here be used anticipate nature likelihood outcomes prioritise management among widespread shifts, while suggesting key priorities future research linking ecology.

Causes and consequences of individual variation in animal movement

Movement Ecology, Journal Year: 2020, Volume and Issue: 8(1)

Published: Feb. 17, 2020

Animal movement comes in a variety of 'types' including small foraging movements, larger one-way dispersive seasonally-predictable round-trip migratory and erratic nomadic movements. Although most individuals move at some point throughout their lives, patterns can vary widely across within the same species: differing an individual over time (intra-individual), among population (inter-individual), or populations (inter-population). Yet, studies (theoretical empirical alike) more often focus on understanding 'typical' than variation movement. Here, I synthesize current knowledge (drawing parallels species types), describing causes (what factors contribute to variation), looks like), consequences (why matters), maintenance persists), implications (for management conservation), finally gaps pieces we are currently missing). By synthesizing scales variation, span work plasticity, personality, geographic variation.

The role of habitat configuration in shaping social structure: a gap in studies of animal social complexity

Behavioral Ecology and Sociobiology, Journal Year: 2019, Volume and Issue: 73(1)

Animal societies are shaped both by social processes and the physical environment in which interactions take place. While many studies observed patterns of inter-individual as products proxies pure processes, or links between resource availability structure, role configuration habitat features shaping system group-living animals remains largely overlooked. We hypothesise that decisions about when where to move, will impact individuals more frequently encounter one another doing so overall structure organization populations. first discuss how spatial arrangement components (i.e. configuration) can shape animal movements using empirical cases literature.

Conceptual and methodological advances in habitat‐selection modeling: guidelines for ecology and evolution

Ecological Applications, Journal Year: 2021, Volume and Issue: 32(1)

Published: Oct. 9, 2021

Abstract Habitat selection is a fundamental animal behavior that shapes wide range of ecological processes, including movement, nutrient transfer, trophic dynamics and population distribution. Although habitat has been focus studies for decades, technological, conceptual methodological advances over the last 20 yr have led to surge in addressing this process. Despite substantial literature focused on quantifying habitat‐selection patterns animals, there marked lack guidance best analytical practices. The foundations most commonly applied modeling frameworks can be confusing even those well versed their application. Furthermore, yet synthesis made yr. Therefore, need both current state knowledge selection, seeking study Here, we provide an approachable overview analyses (HSAs) conducted using functions, which are by far framework understanding This review purposefully non‐technical without heavy mathematical statistical notation, confuse many practitioners.

Frontiers in quantifying wildlife behavioural responses to chemical pollution

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2022, Volume and Issue: 97(4), P. 1346 - 1364

Published: March 1, 2022

Animal behaviour is remarkably sensitive to disruption by chemical pollution, with widespread implications for ecological and evolutionary processes in contaminated wildlife populations. However, conventional approaches applied study the impacts of pollutants on seldom address complexity natural environments which contamination occurs. The aim this review guide rapidly developing field behavioural ecotoxicology towards increased environmental realism, complexity, mechanistic understanding. We identify research areas ecology that date have been largely overlooked within but promise yield valuable insights, including within- among-individual variation, social networks collective behaviour, multi-stressor interactions. Further, we feature methodological technological innovations enable collection data pollutant-induced changes at an unprecedented resolution scale laboratory field. In era rapid change, there urgent need advance our understanding real-world pollution behaviour. This therefore provides a roadmap major outstanding questions highlights cross-talk other disciplines order find answers.

The study of individual behavioral variation, sometimes called animal personalities or types, is now a well-established area research in ecology and evolution. Considerable theoretical work has developed predictions about its ecological evolutionary causes consequences, studies testing these theories continue to grow. Here, we synthesize the current empirical shed light on which are well supported need further refinement. We find that major frameworks explaining existence pace-of-life syndrome hypothesis state-dependent feedbacks models, have mixed support. consequences variation studied at level but less known higher levels such as among species communities. focus this review reevaluate reestablish foundation research: What do know? questions remain?
